| dc.description.abstract | Paratrophurus acristylus sp. n. and Tylenchorhynchus graciliformis sp. n. are described from wheat fields in Libya. Paratrophurus acristylus has a slender (18-21-Aim-long) spear with small basal knobs 2.5-3.2 M™ across, a subclavate female tail with terminal 21-28% hyaline, a postanal intestinal sac filling about three-quarters of tail cavity, and 22.5-23-um-long spicules. Tylenchorhynchus graciliformis is slender (a = 40-49 in females, 45-52 in males) and has a knoblike lip region with 5-6 distinct annules, a 17-18.5-Mm-long spear with large basal knobs 4.5-5 Mm across, female tail with 16-20 annules, and spicules 19-21 ^m long. During a 1980-1981 survey of Libyan wheat fields for plant-parasitic nematodes made by one of us (Z.A.S.), two new species belonging to the family Dolicho-doridae were found. These are described here as Paratrophurus acristylus sp. n. and Tylenchorhynchus graciliformis sp. n. The nematodes were heat-killed, fixed in a 3% solution of formaldehyde, and mounted in dehydrated glycerine after processing them through warm lactophenol. All the measurements were taken from glycerine-mounted specimens. | en_US |
